SHUTTER-OPERATOR.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed April 30, 1907. Serial No. 371,032.

To all Loh-0m it may concern.'

Be it known that I, ROBERT C. SPENoEn, Jr., a citizen'of the United States, and a resident of River Forest, in the county of Cook `l and State of Illinois, have invented certain new and useful Improvements in Shutter- Operators, of which the following is a specification. l

This invention relates to devices for operating easement windows, shutters, and the like.

The object of the invention is to provide a device for this purpose, which will be simple, strong and durable, and adapted for a wide range of application.

To this end the device of my invention consists of the various features, combinations of features and details of construction hereinafter described and claimed.

In the accompanying drawings, in which a device of my invention is fully illustrated, Figure 1 is a perspective interior view of a casement window, showingA my improved device applied thereto for operating the same. Fig. 2 is a sectional view thereof showing a top plan view of my improved device'. Fig. 3 is an enlarged plan section of my improved device on the line 3-3 of Fig. 2. Fig. 4 is a sectional view on the line 4--4 of Fig. 3*; and

Fig. 5 is a view showing a modiiied form of slide for connecting the operating device to the window sash.

For 'purposes of illustration I have, in the drawing, s own a device of my invention applied for operating a easement window.

Referring now to the drawings, A designates the sash of a easement window, and B the stile and C the stool of said window frame. All of the foregoing parts are old and well known in the art and may be of any desired or approved construction.

My improved device for operating the window is as follows: Secured to the stool C- of the window frame, in iXedposit-ion, is a base or pedestal 1 rotatably mounted on which is a head 2, an arm 3 on which is slidably con'- nected to the window sash A. While my invention contemplates any desired or approved form of connection, I prefer that shown in the drawings, in which said arm 3 consists of a bar thelateral edges of which with said wheels.

are substantially parallel with each other and which passes between and is closely embraced by rigid projections on the sash A, vas shown, antifriction wheels 4 rotatably mounted in a bracket 5 secured to said window sash. Said bracket 5 preferably consists of upper and lower members, which operate both to provide a strong and rigid support for said antifriction wheels and also provide a guide to retain the arm 3 in engagementsuch manner, as best shown in Fig. 2, that the window sash will always extend substantially parallel to a line tangent to the convexly curved side of the arm 3 at the point where it engages said antifriction wheels 4. lith this relation it is obvious that said arm 3 will play freely through the bracket 5 in all positions of the window sash.

The bracket 5 and antifriction wheels 4 form, in effect, a slide and while, as shown in Figs. 1 to 3, saidslide is secured to the window sash A in rigid adjustment, my invention contemplates equally'the use of a pivoted slide, as shown in F i0. 5, consisting of antifriction wheels l1 revolubly -mounted between plates 51 pivoted at one end to a bracket 52 secured in fixed adjustment to the window sash A. Obviously with this latter construction, much less exactness will be required in the conformation of the arm 3, as said slide will be free to accommodate T he arm is curved in itself to varying positions of said arm, thus 'i preventing binding, as would occur with a fixed slide in case said arm were not of the proper curve.

As shown, the head 2 ,is rotatably mounted on the base or pedestal l by means of a stud screw 6, which engages a suitable bearing in said head and the lower end of which is threaded into the base or pedestal 1. The head 2 is held in engagement with the stud 6 by a cap 7 provided with a hole or opening rthrough which said st-ud passes and which is held in position by the head of'said stud. Obviously/however, if for any reason desired, the cap 7 may form the head of said Stud.

Rotation, to o en and close the window sash A, is adapter to be imparted to the head- .2 and thus to the arm 3 by means of an operatin lever 8, slidably connected to said hea As shoWn,'the o erating lever 8-.con- .l

cured in the groove 9 by means of the cap 7 and the pivot stud 6, said stud passingthrough a slot 10 in said operating lever, the ends of Which are closed. For convenience in operating the device, `the lever 8 is provided With a grip or handle 11.

The Windowsash A is adapted 'to be secured in any adjusted osition by means of a locking stud 12 on t 1e operating lever 8, which is adapted Ato engage notches 13 in a suitable fixed plate, consisting, as shoWn of a'flange ,14 on the base or pedestal 1, the

edge of Which is preferably substantially concentric with the pivot stud 6. When the stud l2 is in engagement with a notch 13, it is obvious that the lever 8,`the head 2, and

varm 3, and thus the window sash A, will be locked against rotation, thus providing the desiredmeans for securing the sash A in adjusted position. vWhen it is desired to change the adjustment of the sash A, the lever 8 is moved endwise so as to disengage said stud 12 from the notch 13, thus leaving said lever, the head 2 and arm 3 free to rotate to provide for o ening and closing the Window sash A as esired.

A further advantage of the slidable character of the operating lever 8 is that provision is thus made for providinfr an operating lever of desired length to a ord desired ease of operation, while, at the same time,

vthe locking stud 12 and slot 1() may be so arranged that, when in locked position, said operating lever 8 will not project beyond the stool of the window frame. lever 8 will necessarily be so positioned that, When the Window is closed, it will not interfere With necessary movement of said operating lever to effect engagement of the locking stud l2 With the notches 13. Obviously,

in other positions of the lever, said Windowy sash A Will be open and will, therefore, not interfere With the movement of said lever to engage the stud 12 With a notch 13. A
